We report the growth and properties of a-axis oriented GdBa,CusO,-a high T, thin films on (100) SrTi03 substrates by dc magnetron sputtering. It is found that GdBa,Cu,O,-s films on (100) SrTiO, exhibit a-oriented growth at higher substrate temperatures compared with YBaQtsO,-& films. By utilizing low-temperature-grown u-axis GdBazCu,O,_.s films (200 A in thickness) as a self-template, pure a-ax...

Recently, piezoelectric transducer has been used for generation and detection of ultrasound. in medical ultrasound equipment and ultrasound non-destructive inspection equipment. In our laboratory, we fabricated a piezoelectric transducer with PZT poly-crystalline film deposited on the titanium substrate by a hydrothermal synthesis method which is one of crystal growth technology. Fabrication of...

Amorphous fluorinated carbon (a-CF(x)) films have a variety of potential technological applications. In most such applications these films are exposed to air and undergo partial surface oxidation. X-ray photoemission spectroscopy has been used to study the oxidation of fresh a-CF(x) films deposited by magnetron sputtering. The oxygen sticking coefficient measured by exposure to low pressures (<...

Non-fouling surfaces that resist non-specific adsorption of proteins, bacteria, and higher organisms are of particular interest in diverse applications ranging from marine coatings to diagnostic devices and biomedical implants. Poly(ethylene glycol) (PEG) is the most frequently used polymer to impart surfaces with such non-fouling properties. Nevertheless, limitations in PEG stability have stim...

Fixed parameter tractable (FPT) algorithms run in time f(p(x)) poly(|x|), where f is an arbitrary function of some parameter p of the input x and poly is some polynomial function. Treewidth, branchwidth, cliquewidth, NLC-width, rankwidth, and booleanwidth are parameters often used in the design and analysis of such algorithms for problems on graphs. We show asymptotically almost surely (aas), b...

We consider combinatorial semi-bandits over a set of arms X \subset \0,1\ ^d where rewards are uncorrelated across items. For this problem, the algorithm ESCB yields smallest known regret bound R(T) = O( d (łn m)^2 T) / Δ_\min ) after T rounds, m \max_x \in 1^\top x. However, it has computational complexity O(|X|), which is typically exponential in d, and cannot be used large dimensions. propos...

A thin-film transistor (TFT) having an organic-inorganic hybrid thin film combines the advantage of TFT sensors and the enhanced sensing performance of hybrid materials. In this work, poly(3-hexylthiophene) (P3HT)-zinc oxide (ZnO) nanoparticles' hybrid thin film was fabricated by a spraying process as the active layer of TFT for the employment of a room temperature operated formaldehyde (HCHO) ...

Ultrathin glycine-water ice films have been prepared in ultrahigh vacuum by condensation of H(2)O and glycine at 90 K on single crystalline alumina surfaces and processed by soft x-ray (610 eV) exposure for up to 60 min. The physicochemical changes in the films were monitored using synchrotron x-ray photoemission spectroscopy. Two films with different amounts of H(2)O have been considered in or...
